France's Golfech Nuclear Power Plant Reconnected to Grid After Shutdown Due to High Temperatures

French utility EDF (Électricité de France) announced that the Golfech nuclear power plant, located in the Tarn-et-Garonne department, has been reconnected to the grid. Unit 2 of the plant was restarted around noon on August 7, following a forced shutdown on July 29 due to high-temperature weather. At the time of the shutdown, Unit 1 was in the maintenance and refueling phase, making the interruption of Unit 2 more impactful on plant operations. The direct cause of the shutdown at Golfech was that the water temperature of the Garonne River reached regulatory limits. According to relevant regulations, when the daily average water temperature of the Garonne River exceeds 28 degrees Celsius, the plant must reduce reactor power or temporarily cease operations. Since the nuclear plant needs to draw water from the river for...

Rising Seawater Temperatures Prompt New Nuclear Safety Rules: TEPCO Sets Temporary Shutdown Criteria for Kashiwazaki-Kariwa Plant

Tokyo Electric Power Company Holdings announced on August 7 that it has established a set of self-determined criteria for evaluating whether to temporarily halt nuclear reactor operations at the Kashiwazaki-Kariwa Nuclear Power Plant in Niigata Prefecture, in response to rising seawater temperatures in the surrounding area. These criteria are not mandatory requirements directly imposed by external regulatory authorities, but rather proactive measures voluntarily implemented by TEPCO based on safe operational needs. According to the conditions announced by TEPCO, the company will consider temporarily shutting down the relevant nuclear facilities when the 7-day average seawater temperature in the waters surrounding the plant exceeds 31 degrees Celsius, when water temperatures above 34 degrees Celsius are observed, or when water temperatures above 33 degrees Celsius persist for 12 hours. These numerical thresholds indicate that seawater temperature has been incorporated as a key variable in nuclear power plant operational risk management.

Canadian laboratory validates molten salt separation process with real spent fuel, extracting nearly 90% of plutonium in 24 hours

A chemical experiment in Canada involving real commercial reactor spent fuel has achieved noteworthy progress. Canadian Nuclear Laboratories, in shielded hot cells at Chalk River, used irradiated spent fuel from CANDU reactors to validate the first phase of Moltex Energy's waste-to-stable-salt process. The experiment showed that within 24 hours, 89.4% of the plutonium was transferred into the molten salt; by 60 hours, this proportion rose to 94.3%. Meanwhile, the vast majority of uranium remained outside the salt phase, indicating that the process exhibits strong selectivity in separating target elements. This process, named WATSS, is not a plutonium purification route but rather a group separation technology. In addition to large quantities of uranium, spent fuel contains fission products as well as transuranic elements such as plutonium and americium, the latter being a significant source of long-term radiological risk. WATSS uses high-temperature chloride molten salt and specific reducing metals to convert transuranic oxides into salt-soluble forms, while most uranium oxides remain solid. In this experiment, researchers used niobium as the reducing metal; after 24 hours, only 0.05% of uranium entered the salt, dropping to 0.02% after 60 hours, demonstrating that it does not carry large amounts of uranium into the molten salt system.

Danube Water Level Temporarily Recovers, Hungary's Paks Nuclear Power Plant May Continue Reduced-Power Operation

Hungarian Prime Minister Peter Magyar said on August 7 that due to rainfall in Austria, the Danube water level is expected to temporarily recover in the near term, which will help improve cooling conditions at the nuclear power plant, but the Paks Nuclear Power Plant, which supplies nearly half of Hungary's electricity, may still continue to operate at reduced power. In a social media video, Magyar said the current situation at the Paks Nuclear Power Plant remains very difficult. Affected by persistent high temperatures and historically low Danube water levels, the plant has been operating at approximately 10% output since last week. At a subsequent press conference, he stated that Hungary must find a solution for the operation of the Paks Nuclear Power Plant, because "the Hungarian economy cannot function for months without the plant." Previously, the government had called on businesses and residents to reduce electricity consumption in the evening and dim the decorative lighting of historic buildings in Budapest to alleviate power supply pressure.
